Here we go : my 3 favorite parts of the Pa4x (hard choice there are so many)
- Sound engine, is more advanced then any other arranger and many synth workstations
- Styles sound incredible and the engine is more advanced then Yamaha's
- the songbook combined with the setlists make a perfect tool
My 3 least favorite things of the pa4x (had to think really hard to find any)
- no access to the huge player created databas of styles that Yamaha has
- no 88 key or desktopmodule version
- only 4 sounds and 1 insert and 2 master effect for keyboard parts
